You realize the "demo" tag means business. You get the router running, but certain high-speed throughput features or advanced APIs are throttled until you apply a proper license, leaving you staring at a perfectly configured but limited virtual machine.
Here’s a blog-style post based on your keyword — written for network engineers and lab enthusiasts.
